Highlights: BMW’s biggest luxury sedan gets a touch of green from a supplemental electric motor and battery pack. It still offers all the luxury of a normal 7-Series, but lets its owners feel better about driving around a gigantic car.
Our Opinions: I achieved 44.1 mpg over my 40-mile, mostly highway commute to work. I started with a fully charged lithium-ion battery pack and resisted several urges to pick up the pace. In doing so I was rewarded with a remarkably quiet and smooth ride to work. It was comfortable, calm, and boring. But that was a choice. I could’ve simply switched to sport and rifled through traffic with my usual insatiable need to reach my destination sooner. This 7 does either with aplomb.
Hearing four-cylinders, instead of eight or twelve, momentarily let me down, but truthfully it’s time to concede that’s a bygone era ready to be put to pasture. You’re never wanting for power in the 740e with the addition of a torque-all-the-time electric-motor supplant. And, when the tank was empty, I stopped at the pump and filled it again with only 10 gallons of fuel. Impressive for something this big and plush.
